Does Java 8 support interpolation

Question

Groovy supports string interpolation operations. Here is an example

def name = "Tom"
println("Hello my name is ${name}")

Does Java 8 support string interpolation as the way Groovy does?

Any answer, greatly appreciated. Thanks

Java8 has nothing to do with this. For formatted console output, you can use printf() or the format() method of System.out Try this out.

System.out.printf("My name is: %s%n", "Tom");

For formatted console output use of String.format is recommanded. System.out.println(String.format("My name is: %s%n", "Tom"));

When logging a message there are several important requirements which must be fulfilled:

The user must be able to easily retrieve the logs The format of all the logged message must be uniform to allow the user to easily read the log.
Logged data must actually be recorded.
Sensitive data must only be logged securely.
If a program directly writes to the standard outputs, there is absolutely no way to comply with those requirements.

That's why defining and using a dedicated logger is highly recommended. org.slf4j.Logger is one of the standard Logger factory and is easy to use.

private static final Logger LOGGER = LoggerFactory.getLogger(<ClassName>.class);
LOGGER.info("My name is: {}", "Tom");
